Many homeowners with foundation cracks seek quick DIY solutions to repair the damage as quickly and efficiently as possible. However, quick solutions such as caulking and sealing cracks will only provide a temporary cosmetic solution if you have severe foundation damage. To effectively fix foundation cracks, you need to address the root cause of the problem.
Sometimes, foundation cracks indicate more than what meets the eye: an underlying structural issue. In this case, simply sealing cracks will not prevent your foundation from continuing to settle into the ground. So, how do you know if your foundation cracks are severe enough to warrant structural repair?
Vertical and diagonal cracks in your home’s foundation are most often a sign of natural settlement and not necessarily a sign of structural damage in your home. If the crack seems even when you run your finger across it, that probably isn’t a sign of a significant problem, and you should be able to do the minor cosmetic repair yourself.
Larger cracks that aren’t serious enough to indicate foundation failure may be repaired by you or a contractor. A homeowner can repair simple foundation cracks without drilling holes in the foundation walls or using high-pressure injection systems. Cracks that Airlift Concrete Experts should fix leak because we have the tools, products, and know-how to repair them.
Cracks larger than 1/4” in width, particularly horizontal cracks and those that leak, are a different matter, and you should consult Airlift Concrete Experts to determine whether further repairs should be implemented to avoid serious foundation problems or even foundation failure.
The following are various methods used by homeowners and professionals to repair foundation cracks. Some methods are more reliable and longer-lasting than others.
Often, homeowners may try to patch a leaking crack with caulk. This repair typically lasts only 6 months to a year because water will continue to seep into the crack behind the patch. Eventually, efflorescence, a white mineral salt in the groundwater, will break the seal and allow water to seep in again.
Sometimes, homeowners or contractors attempt to repair the crack by chiseling out an inverted V-groove and filling it with hydraulic cement. While the cement will fill the hole, it doesn’t bond with the cement. Typically, within a couple of years, the concrete wall will expand and contract with changes in temperature and moisture, causing the plug to leak again.
Epoxy crack injection is an effective method for repairing cracks in poured concrete foundations. Airlift Concrete Experts is highly experienced and knowledgeable about this type of repair.
This type of repair is applied from the inside of your basement, so there is no need for excavation on the outside. Once the epoxy is used, it usually takes about 5 hours to cure. Epoxy injections will permanently seal cracks and provide structural integrity as the epoxy is stronger than the concrete itself.

Sometimes, foundation cracks continue to form due to severe water issues affecting the foundation. In this case, excavation is required. All structures, sidewalks, gardens, and landscaping are removed during the excavation process. Then, multiple layers of synthetic waterproof material are installed to prevent further movement of the wall and prevent water from affecting the foundation.
After the waterproofing is installed, everything is returned to its original position. It is essential to note that the excavated soil will settle during the first year, making regrading necessary the following year.
To effectively repair a leaking foundation crack, injecting a high-viscosity polyurethane polymer is the best method. Unlike other fillers, polyurethane bonds well to both wet and dry concrete, and its high viscosity allows it to fill even the tiniest hairline cracks.
With the ability to expand up to 20 times its volume, polyurethane polymer forms a durable seal that effectively accommodates wall movement and shifting. Additionally, it is more economical compared to traditional exterior methods, as it requires no extensive excavation and can be completed in just a few hours.
